Rear sprocket 420 48T D48mm

Rear sprocket 420, 48 teeth, D 48 mm – a toothed wheel on the rear hub. Together with the front sprocket and the chain it forms the final drive ratio: the tooth count decides whether the machine accelerates faster or reaches a higher top speed on the straight.

• Marking 420 – it must match the marking on your chain, otherwise the teeth will not match its pitch
• 48 teeth – the number from the name; it is not cast onto the sprocket itself
• The drawing marks 48 mm twice – between the upper mounting holes and between the lower ones
• Four mounting holes, four weight-reducing cutouts; steel, unpainted
• Replace all three parts together – a new chain wears quickly and stretches again on worn teeth
• Other rear sprockets for 420 in the list have 37 and 38 teeth; this one has the most teeth in the 420 line, so it gives the shortest gearing
• You'll find other sprockets in the "Sprockets" category, and chains and their joining links in the "Chains" category

We write only what we know. Whether 48 mm is also the centre bore diameter, the drawing does not say – there this number is drawn only between the mounting holes. Before ordering, copy the marking from your chain's side plate, count the teeth on your old sprocket, and measure the mounting-hole circle and the centre bore – we will check it before you order.
